The Illinois Butterfly Monitoring Network is a citizen-scientist program that monitors the health of butterfly populations throughout northeastern and central Illinois.
Each summer, trained volunteers collect and submit butterfly data from an assigned site. Volunteers commit to conducting at least six site visits between June 1 and August 7, completing four of them before July 20. During the first year they volunteers, participants learn to identify 25 different butterfly species, and they learn another 25 species the second year.
Through analysis of the extensive database generated by citizen scientists, populations trends of species throughout the Chicagoland area are starting to emerge. These results will assist land managers in more effective conservation of the state's butterflies.
Many important sites do not yet have butterfly monitors, and project coordinators continue to look for more volunteers. Join the fun!
